Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
tert-Butyl 7-methyl-2,3-dihydro-1H-spiro[isoquinoline-4,4'-piperidine]-1'-carboxylate (CAS 906369-89-9) is a high-purity analytical reference standard with the molecular formula C19H28N2O2 and a molecular weight of 316.44 g/mol.
The molecular framework of tert-Butyl 7-methyl-2,3-dihydro-1H-spiro[isoquinoline-4,4'-piperidine]-1'-carboxylate (C19H28N2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures tert-Butyl 7-methyl-2,3-dihydro-1H-spiro[isoquinoline-4,4'-piperidine]-1'-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
